Princess Daisy

"Princess Daisy is the ruler of Sarasaland, a country that is composed of four kingdoms (Birabuto Kingdom, Muda Kingdom, Easton Kingdom, and Chai Kingdom) and located very far away from the Mushroom Kingdom. One day, a mysterious space alien named Tatanga invades Sarasaland. In addition to hypnotizing all the country's inhabitants to enslave them into his army, Tatanga kidnaps Daisy in order to marry her and make her his queen, thus setting the events of Super Mario Land into motion.

Upon hearing of this, Mario journeys to Sarasaland to rescue Daisy and bring peace to the country by traveling through each of its four kingdoms in order to stop Tatanga and his invasion. Throughout the game, enemies disguise themselves as Daisy to trick Mario into believing he has rescued her, only to reveal their deception seconds afterward and run away. Although Tatanga ultimately manages to escape, Daisy is rescued regardless and Sarasaland returns to peace, resulting in Daisy thanking Mario with a kiss as she flies away with him in an airplane......

In addition to her initial design being strikingly similar to Princess Peach's, NES Open Tournament Golf furthered the notion of Daisy being a counterpart to Peach by having her as Luigi's caddie. Daisy and Luigi's relationship has since progressed into a reciprocal, yet subtle romance that has been demonstrated in numerous instances, such as her victory scene in Mario Power Tennis; her personal race course in Mario Kart Wii; and her trophy information in Super Smash Bros. Melee and Super Smash Bros. for Wii U. Daisy has also forged a close friendship with Peach upon traveling to the Mushroom Kingdom,[1] and has remained a friend of Mario's ever since their first encounter.

Unlike Peach, however, Daisy is an energetic tomboy.[2] Despite being featured almost exclusively in spin-off games since her debut, Daisy's personality has nevertheless been explored to a degree. In particular, Fortune Street reveals that Daisy is energetic to the point of being impulsive, eager to take on challenges, and even brash enough to talk down to the likes of Wario, Waluigi, and Bowser."
